High Tension Terminal

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

it was basically a woodscrew-pattern intended to have the wire twisted onto it without a terminal. And the coil was a Delphi model that when I dug around, seems to have DNA tracing back to lawn tractor-intended-applications. If the post-14s are just putting a terminal onto the woodscrew, well, it's pretty makeshift anyways (though still probably better in being able to be connected and disconnected without reduction in conductivity of the wire's resistance core)

So I'm going to have to tread into the unknown by myself? :o

OK, let's start at the beginning. What is it that is unknown? What information are looking for that isn't in these and the linked threads?

How is the wire attached at the coil end? Does it pull out or unscrew? There is a photo of a crimped teminal on the wire, but it isn't clear (to me) how the terminal connects inside the coil.

A screw is inside the coil. The terminal is pushed onto this with somewhat of a click.

Has anyone got a definite answer exactly how this thing is attached at the (Delphi) coil end? For example, I don't want to be pulling or pushing things where instead I should be unscrewing, or vice versa! :o
Unscrew the lead counter clockwise. The Delphi end is resin fixed into the coil.

Pulling it will make it come off, but then you won't be able to screw it back on and get it to bite and bed down. There is a tiny clip at the end of the terminal
I suspect a lot of lead issues I had were due to a previous owner/service agent pulling the leads.

As for getting a set of terminals - I kept and old set of leads and will be removing the end and making a new set.

OK, thank you! :bow:

So unscrew, do not pull

I think I'm going to do same as you, reuse existing. I have an HT lead crimping tool.

Worked for me - The photo shows one that has been pulled - it is splayed open and the circlip is also open. Like this it won't screw back in and bed nicely. Simple job just to pinch them down again if you do re-use them. The HT lead core is folded along the back of the terminal.

I guessed that was the case. So in that respect like any other crimp on teminal.

OK so one can kinda see why they think they need to have some weird screw-on metal bit instead of...
as near as I can tell, this is meant to take a spark plug wire and screw it on there so that it catches the inner core and tightens down, then you slide the rubber cap over the big part and call it a day, no connector needed
I agree I can't see why a copper core lead can't screw in there. Only one way to find out!

I am reminded of a Magneti-Marelli coil, I think I'm right, as was used on the old Moto Guzzi's; the HT coil terminal comprised of a spike that went up the middle of the wire and then the wire was prevented falling out by a compressible grommet and a screw cap, so there are worse ideas out there .. :D

Appendix (edit): if the screw cap cracked and fell apart, and it could happen, you were basically fooked, you couldn't just buy a new cap even if the coil wasn't obsolete and unobtainium, which it probably is now.

Using some pliers, you can roll an actual normal everyday high tension terminal available at the local auto parts store into something that will screw on to that screw but it will get loose just like the stock wires do. The NGK resistor spark plug caps that I used on my copper core wires have a similar setup to what you describe, but it appears to be more robust.

From my old notes -try MSD coil terminals. You'll have to match the pin socket ID and the wire diameter.

There's a post back in '14 from when I was working on a reverse shifter install that wasn't going as advertised because the coils wouldn't fit on the mount. After relocating the coils I had to shorten and reroute the plug wires. The wires didn't have coil-end connectors and were just pushed onto the coil pin. I gave up searching for replacements. It was easier to order a new set of wires ---- !!!!WHICH CAME WITH CONNECTORS!!!!---- and shorten them from the spark plug end.

I have, and highly recommend, the MSD strip/crimp tool. Works like a charm and prevents over crimp from damaging the plug wire sheath.

In my case the reason the non-terminal ends were failing was the central carbon fibre conductor. It's like a very thin ribbon. Repeated insertion spread out the fibres leading to poor contact with the coil terminal.

This is why I want to go to copper core! I hate that stuff. Always have. :gahhh:

Thanks for all your replies.

Weather in UK still iffy, maybe Thursday before I look into it some more
